I have been using Gem Cleaning for the last 8.5 years. They have consistently proved to be efficient, thorough and reliable. Cleanliness and hygiene is of paramount importance in our dental practice and Gem always maintain their and our high standards. They are always willing to please and accommodate our cleaning needs. Not only do they clean the practice but they also clean and wash our windows and at six monthly intervals they give the floors a special deep clean. We are very happy with Gem and would not hesitate to recommend them to any business
